World leaders are meeting in Ethiopia this week for a summit, which will lay the ground rules for a fairer world of inclusive, low-carbon growth.
They will be trying to decide how to fund a series of Sustainable Development Goals between 2015 and 2030.
Those goals will replace the UN's Millennium Development Goals, which expire at the end of the year.
